BTJ'I'LIDING-BILOCK;

Application filed September 24, 1919. Serial No. 325,926.

To all whom it may concern:

Be it known that I, JOHN R. BAUMANN,

a citizen of the United States residing at Red Win in the county of (droodhue and State of Minnesota, have invented certain new and useful Improvements in Building- Blocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains t make and use the same. I

The object of the invention is to provide a building block of such aconstruction as to provide for an overlapping break-joint relation with similar blocks in the same and also in adjacent courses of the structure, and also for providing an interlocking relation with similar blocks both in the same and the adjacent courses so that in the erection and formation of buildings, silos, elevator shafts, drains, sewers, water mains, culverts, and the like the use of cement or. plaster may be dispensed with as a means of maintaining the proper relation of the building blocks, the use thereof, if employed, being merely to serve as a filling or packing for the joint to insure the production of an air-tight structure; and furthermore it is the obj ect of this invention to provide an improvement or development of the principle of building block construction disclosed in my co-pending applications, numbered 227 ,093 filed April 6,

. 1918, and 275,349 filed February 6,1919, to

the end that the advantages secured by the building blocks shown in said former applications in relation to the interlockjsecured' between the elements of a single course may be extended to the courses respectively above and below or at opposite sldesof each course,

so that the resultingstructure, in effect, shall have the qualities and characteristlcs, in so far as offering resistance to either internal or external pressure, of a unitary .device, or of'a wall consisting of a single block of which all of the elements are integrally relatedand united.

Further objects and advantages of theinvention will appear in the course of the following description of a preferred embodiment thereof, it beingunderstood however that changes 1n form, proportion and details 7 may be resorted to within the scope of the claims without departing from the principles involved.

Specification of Letters Patent.

In the drawings: 7 V Figure 1 is aside view and Fig. 2'isa horizontal sectional view of a section of wall Fig. 4 is a similar view of a block de-'.

signed for use in the construction of a device havlng a curved or cylindrical wall. Flg. 5 1s a slmllar view of a l1ne block in which the offset or shoulder between the I members is arranged in a slightly different relation to the members, to wit, on a transverse'medial line as distinguished from the diagonal line of the offset or shoulder as shown in Figs. 3 andt.

Figs. 6 and 7 are perspective views respectively of blocks,-.also indicated in Figs. 1

and 2, andhereinafter referred to specifi cally as a key-block and a corner block, wherein the offset or shoulder is arranged in the same relation to the members as indicated in the forms shown in Figs. 3 and 4.

Fig. 8 is a plan view of a line block showing optional planes of ofi'set between blockmembers.

Each block comprises two identically constructed members preferably cast or molded to form unitary or integral structure and which may be regarded as meeting and being united either on the transverse medial plane or line indicated by thedotted line.

At-A of Fig. 8, or the plane indicated by the dotted line B'B of Fig. 8,"or upon the longitudinal medial plane indicated by the dotted line CC of Fig. 8. Each of these members is provided withinterlocking elements for engagement with corresponding I elements on the adjoining block in the struc- 'ture, andone of the elements of each block is offset from the other member on' one of thesemeeting or uniting'planes, the direction of ofiset being parallel with the wall.

face surfaces Dof the blocker perpendicular to the course face surfaces E thereof to.

. form shoulders 10. In the construction'of line blocks indicated in'detail in'Fig. 3, the identically constructed members are repre sented as meeting upon a diagonal plane'indicated bythe offset shoulder 10 disposed nal medial lines of the block, each of said members having a wall face surface D and diagonally to the transverse and longitudian inner longitudinal surface provided with male and female interlocking elements 11 and 12. Also the inner end of each blockmember disposed near the transverse medial line of the block is provided with male and female interlocking elements 13 and 14E while the outer or remote ends of said block mem- V bers are provided with male and female interlocking elements 15 and 16.

wall structure in interlocked relation with other blocks of the same or similar structure, it will be seen that both transverse and longitudinal interlocking relation is established' between said adjoining -or related blocks and moreover, due to the fact that one member of each block is offset from the other member in a direction parallel with the wall face surfaces or perpendicular to the course face surfaces there is an interlock between.

the course in which said block is locatedand the courses above and below the same.

In the corresponding construction shown in Fig. 4. the only difference consists in the fact, that the block as a whole is given a slight curvature upon a radius adapting it to be: used in the construction of an arched or cylindrical wall such as may be preferred in the construction of silos, drains, culverts andjthe like.

In thecon'struction shown in Fig. 5 the only difference resides in the fact that the offset between the members is made on a plane corresponding with the transverse medial linev of the block instead of upon a diagonal line as indicated in Fig. 3. Figs. 6 and 7 show the application of the prin- 7V ciple of. offsetting the members as applied to reversingor key blocks designed for changing the'order of the line blocks, and

. corner blocks arranged at the corners of angular wall structure. As will be understood from an inspection of the drawings,

with particular reference to Figs. 1 and 2, the interfittingof the adjacent blocks both in the same and adjoining courses must be efiected by a transverse movement of each block with relation to those with which it is interlocked, that is. to say a movement in a direction parallel with the wall faces or perpendicular to the course face surfaces,

and when the interlock has been effected,

the angular displacement of one block with relation to the next or the others with which it is interlocked is prevented even though.

cement or plaster maynot be used in the joint, owing to the overhangingrelation of the male elements at the inner end edges. of

the block members with the interlockedmale members of the outer or remote end edges of the adjoining blocks. Obviously the offsetting of the members of each block serves to guard: against any shifting between the blocks in adjoining or adjacent courses and hence the binding together of the elements hen a block of this construction is arranged in a with complementary 'inner of the wall to effectually resist both external and internal pressure.

What is claimed is:

1.. A building block for overlapping break-joint relation with. similar blocks in the same and adjacent courses, the same consisting of similar reversely disposed members meeting ata common transverse plane of the block, and respectively having outer opposite wall' face surfaces and provided with complementary inner interlocking faces, one of said members being offset from the other in a direction perpendicular to the course.

2.. A building block for overlapping break-joint relation with similar blocks in the same and adjacent courses, the same consisting of similar reversely disposed mem--' bers meeting at a common transverse plane of the block, and respectively having outer opposite wall face surfaces and provided interlocking faces, one of said members being offset from parallel with they wall face surfaces.

i. A building block for overlapping being offset from the other in a direction break-joint relation with similar blocks in the same and adjacent courses, the same consisting of similar reversely disposed members meeting at a common transverse plane of the block and respectively having wall face surfaces and intersecting course face surfaces of which the former are parallel and are disposed at anangle to said 7 meeting plane between the members, said members being provided with complemental interlockingelements and one of the members being offset from the other on said meeting plane in a direction perpendicular to the courseface surfaces. 1

5. A building block for overlapping the same and adjacent courses, the same consisting of similar reversely disposed members meeting at a common transverse plane of the block and respectively having opposite longitudinalwall face surfaces atan angle to said meeting plane and each having transverse inner and outer'end surfaces located at different dlstances from saidtransverse meet-mg plane and provided respecbreak-joint relation with. similar blocks in tively with male and female interlocking elements, one of said members being offset from the other member in a direction parallel with said meeting plane and parallel with the wall face surfaces. v

6. A building block for overlapping break-joint relation with similar blocks in the same and adjacent courses, the same consisting of similar reversely disposed members meeting at a transverse medial plane of the block and each having longitudinal wall face surface located on oppo-' site sides of and equal distance from a 1ongitudinal medial line of the block, and each having transverse inner and outer end surfaces located at different distances from said transverse medial plane and provided respectively with male and female interlocking elements, one of said members being offset from the other on said meeting plane in a direction parallel with the wall face surfaces. f

In'testimony whereof I afiix my signature in presence of two witnesses.
